This invention relates to rapid sequence of actions on stock, asperforating strips of material. This invention has utility whenincorporated in continuous feed drive of narrow sheet stock,

"' whether metal or photographic film, and establishing a series ofholes therein definitely spaced.

Referring to the drawings:

Fig. 1 is a side elevation of a dark chamber housing for the device asadapted to film which may be in the sensitive state;

Fig. 2 is a view of the operating parts, with the housing or darkchamber removed; I

Fig. 3 is a view on theline III-III, Fig. 2, looking at the slitter forsub-dividing the strip lengthwise; I

Fig. 4 is a section on the line IV-IV, Fig. 2, showing the supply reelfor the strip stock as film;

Fig. 5 is a section on the line V-V, Fig. 2, showing the punch andcooperating die;

Fig. 6 is a view of a portion of the ribbon stock or strip as in thesupply roll to the right of Fig.2, say of sixteen millimeterphotographic film;

Fig. 7 is a fragment of strip stock having the greater number of holestherein and the strips cut in two, thereby forming an eight millimeterstrip as in the film range as supplied to the re- Housing or dark room Ihas removable closure.

2. Protruding from the housing or dark chamher I is shaft 3 havinghandle t as a manual drive. In this chamber or housing I and anchoredtherewith by screws 5 (Figs. 2, 8, 9) is frame 6 providing bearing forthe shaft 3. This shaft 3, as

extending through the frame 6, has thereon feed roller 7, in thisinstance having teeth 8 for entering openings 9 in sixteen millimeterfilm III (Fig. 6). Pin I I anchors gear wheel I 2 with theshaft 3 asdoes pin I3 anchor the crank A. This gear wheel I2 is in mesh with gearI i fixed with shaft I5, extending through the frame 5 parallel to theshaft 3. As projecting from the opposite side of this frame 5 the shaftI5 carries pulley I6. Split ring il in groove I8 anchors this shaft I5against longitudinal shifting as to the bearing in frame 6 and therebyholds the gear wheels I2, I L-in proper mesh relation.

From this pulley I5 extends helical coil endless belt I9 about pulley2G, fixed with shaft ZI in bracket 22 and carrying re-winding reel 23for the worked strip stock. This bracket 22 is an cho-red with the frame6 by screws 2% and has extending oppositely from the arm 22 bracket arm25 (Figs. 2, 4) having therein shaft 26 with friction washer 2 7 on oneend thereof held by screw 23 to pull split ring Zil in groove 3? as acollar against the opposite side of the bearing of thebracket 25,thereby providing protruding shaft portion inward from cone screw SIadapted to center and mount supply reel 32 on this protruding shaft tohave frictional resistance adjusted therefor at the washer 27 forunwinding the strip stock I0 as pulled therefrom by the feed roller 1.Screws 33 in the frame 6 (Fig. 8) mount guide brackets 34. on oppositesides to carry spacer roller 35 therebetween as a directing device topreclude the film Hi from whipping clear of the teeth 8 and thereby inpositive continuous feed uniform travel position as to this feed shaft3.

This film from the feed roller I of the feed device passes upward byguide-way 36 past die or die block 3?, opposing which is (Figs. 5, 10)punch 38 having cutting heads 35B, reciprocable to register withopenings E0 in the die block 3'5. From these openings 58 there isenlargement extending to tube II as a directing means or duct forconducting away from the machine the punchings from the film It, say asfor intermediate holes 2.

The gear I i is in mesh with pinion 43 (Fig. 2) on shaft M in the frame6, parallel with the shaft 3. This shaft M has thereon fly wheel orrotating Weight mass 45 (Fig. 10) anchored in desired angular positionrelatively thereto by set screw 46. Additionally, this rotating flyweight has radial way M in which is located projecting adjustable bevelface or cam 38, the radial position of which is locked by set screw 39.In the continuous rotation of this drive shaft 3 for the feed, there isin this intermediate gearing a speed-up drive for this cam 48 at sucheffective speed that the action of this cam in striking impactor orpunch 38 projects such into and through the stock way 36 and hereinpasses between follower roll pair 52, 53. The roll 52 has marginalflanges 54 to hold the stock in alignment therewith, while the companionroll 53 has slitter rib or cutter 55, which in the adjusted position ofthese rolls as on point bearings 56 (Fig. 3) holds this position forslitting or cutting action in eifecting severing line 51 in the stripI'll actuated therepast producing double strips or multiple strips '58,59 (Fig. '7). However, these may be separately wound or continue as aunit, and in continuing as a unit may pass from this slitter roll pairabout the hub of re-winding roll 23, to be rewound thereon as the stripstock or film for this completed operation in conversion from sixteenmillimeter to eight millimeter film as in the instance herein disclosed.

The speed-up for the impactor action of the punch as to the feed devicein the lineal rate of travel relation is effective in the continuousfeeding drive with seemingly no disturbance for accuracy in registry ofthe punchings. However, having in mind possible heavier stock oroccasion for somewhat slackened speed in the actual punch operation,with maintenance of a linear speed rate for the feed, there may beadopted crank 60 (Fig. 11). Drive gear 6! in mesh with pinion 62 fixedwith elliptical gear 63 in mesh with complementary elliptical gear 64,at the crank 60, fixed with fly weight 65, carrying cam 66. This wouldmean there is variable speed-up as to the feed shaft directly drivenfrom the gear 64 but with a relatively angularly retarded section whenthe punch action is efiected by the cam 66.

The disclosure herein involves narrow strip stock, say even as initiallypunched, or control for certain sequence of markings with themultiplication of such operations efiected with a degree of rapidity ina continuous feed, even as to punching operation with a degree ofaccuracy efiective for a superior output in motion picture film, withthe punching operation efiected as rapidly as sixty feet per minutelineal travel of the strip film.

What is claimed and it is desired to secure by Letters Patent is:

A frame and a mechanism mounted thereby embodying a feed device, animpactor, a speed multiplying intermediate transmission gearing for theimpactor from the continuous feed device, a common drive for the deviceand impactor effective through said gearing, said impactor embodying afly wheel, a punch, said fly wheel having a continuous peripheralsurface provided with a limited duration extent projection of contactfor thrusting the punch, yieldable means holding said punch toward thefly wheel, an annular die opposingthe punch, and a guide for strip stockbetween the die and punch, said die having fixed therewith and extendingtherefrom a receiver for punchings cut from the stock by the die asacted upon'by the punch.
